Despite her criticizing Boughton out for having "one foot out the door," referencing his failed gubernatorial bid three years ago, Boughton won the race with nearly 70 percent of the vote.

While some believe an unopposed race would give Boughton more time to focus on another gubernatorial run next year, the mayor said he has yet to make a decision about that race and he remains committed to the city of Danbury.

"Nothing has really changed from yesterday to today," he said Tuesday. "My plan is to run a vigorous mayoral campaign."

DaSilva said despite not having a mayoral candidate, the party has a strong field of candidates for the City Council, including CityCenter managing director Andrea Gartner and veteran education board member Bob Taborsak.

Council minority leader Tom Saadi said candidates on the under ticket will have to work that much harder to reach out to constituents and get out the vote.

"It puts a lot more pressure on us to knock on a lot of doors and get people to come out and vote on Election Day," he said.

"Even without a challenge to the mayor, it's still important for people to vote in their municipal elections and decide who their local elected officials will be."
